I've been testing these pools for about 24h so far :
Coinotron - the most stable results so far 314.4/298.6/272 Mh/s (Rejections about 7-8%)
GHash (multi) - pretty good results, higher rejections than with coinotron
LiteGuardian - decent, but for now worser than coinotron and GHash
Clevermining - too high rejection percentage - waiting for some improvements here
give-me-coins - unstable, rejections about 40-50%, restarting titan
What have you found regarding profitability for the multipool vs straight ltc/doge combo?
